Abstract (en)
[origin: WO2004059817A1] The aim of the invention is to improve the electrical and mechanical properties of a litz wire conductor (1) for coils of electric machines. For this purpose, the interstices between the filaments (3) of a conductor (1) are filled with an elastic potting compound (4). In order to allow for more regular marginal field intensities in the circumferential area, the potting compound (4) can be electrically conducting. For filling the interstices, the individual filaments (3) can also be provided with a coating which accelerates curing of the steeping agent.
